DIAMETER ; the straight line drawn through the centre of a circle, and touching the two opposite points of the circumference. It thus divides the circle into two equal parts, and is the greatest chord. The radius is half this diameter, and consequently the space comprehended between the centre and circumference of a circle. (For the magnitude of the diameter, in comparison with the circumference, see Circle.)
